Annual recurring revenue multiplied by an ARR multiple driven by growth and profitability.
Most SaaS businesses are valued as a multiple of Annual Recurring Revenue. The multiple itself is set by growth rate, gross margin, net retention, and profitability — usually framed through the Rule of 40. In 2026, median private SaaS deals clear around 6x ARR; top-quartile growth-and-margin businesses fetch 12x or more.
Growth rate plus profit margin should sum to 40 or more.
Rule of 40 says that growth percentage plus profit margin percentage should be at least 40. A SaaS growing 50% with a -10% net margin scores 40 — healthy. The higher the R40 score, the higher the ARR multiple buyers and investors will pay.
Median private deals land near 6x ARR; top-tier go 12–18x.
The 2021–2022 bubble pushed multiples above 20x for hyper-growth names. That era is over. In 2026, median private SaaS deals close around 6x ARR. R40 stars (>80) still command 12–18x. Sub-scale or slow-growing SaaS may transact at 1–3x ARR.
Private companies trade at a 25–40% discount to public SaaS.
Public SaaS companies like Salesforce and HubSpot enjoy liquidity, scale, audited financials, and brand. Private SaaS businesses trade at a 25–40% discount because buyers price in concentration risk, key-person risk, and integration cost. Your model output is private-fair-value, not a public ticker.
The mechanics in short answers — no jargon, no upsell.
ARR is the rhythm of a SaaS business. Investors value the predictability of recurring revenue, not one-time services or hardware. Enter your current run-rate ARR.
Add your YoY growth rate to your net profit margin. A 60% grower with -20% margin scores 40 — fine. A 30% grower with 20% margin also scores 50 — excellent. The higher, the better the multiple.
R40 above 80 unlocks 12–18x ARR. 60–80 earns 8–12x. 40–60 lands in 5–8x. Below 40 drops fast — 3–5x at 20–40 and 1–3x below 20.
Gross margin above 80% adds a +1x bump; below 60% subtracts 1x. Annual churn under 5% adds +0.5x; over 15% takes -0.5x. The output is a low–high band, not false precision.
Designed so anyone can model their situation in under a minute, with or without a finance background.
Low, mid, and high estimates based on your growth, margins, and churn — not a single suspicious number.
The industry-standard composite that buyers, VCs, and PE firms actually use to set multiples.
Multiples calibrated to current private-market reality, not the 2021 bubble or 2009 lows.
High gross margin earns a multiple bump; weak unit economics get a haircut, automatically.
Low churn means stickier ARR and a higher multiple. The model reflects that explicitly.

A SaaS valuation calculator estimates what a software-as-a-service business is worth, usually as a multiple of Annual Recurring Revenue. This tool uses ARR, YoY growth, gross margin, net profit margin, and churn to produce a low–high valuation band based on 2026 market comps and the Rule of 40.
In 2026, the median private SaaS deal closes near 6x ARR. The 2021–2022 bubble briefly pushed peak multiples above 20x, but that era is over. Top-quartile businesses with strong Rule of 40 scores still earn 12–18x. Slow-growing, low-margin SaaS may transact at 1–3x ARR or below.
Rule of 40 (growth rate + profit margin) is the most cited single metric in SaaS valuation. Above 40 is healthy; above 60 is excellent; above 80 is rare and commands premium multiples. Below 20 indicates either weak growth, weak unit economics, or both — and multiples compress sharply.
The SaaS standard is 70–80% gross margin. Above 80% is excellent and earns a multiple bump in this calculator. Below 60% suggests either heavy infrastructure cost, a services-heavy revenue mix, or pricing power problems — and the multiple takes a haircut.
Low annual churn (under 5%) signals product-market fit and sticky revenue, earning a small multiple premium. Annual churn above 15% drags valuation down because it means ARR is leaky — every new dollar has to first replace a lost one.
Public SaaS like Salesforce and HubSpot trade with liquidity, scale, audited financials, and brand premium. Private SaaS carries a 25–40% discount for illiquidity, concentration risk, key-person risk, and the cost of buyer due diligence.
ARR — recurring revenue only — is what drives SaaS multiples. One-time services revenue, hardware revenue, or implementation fees should be excluded or valued separately at much lower multiples (typically 0.5–1.5x).
No. This calculator gives you a defensible starting range using 2026 comps and the Rule of 40. A real transaction requires a banker, a quality-of-earnings study, and buyer-specific synergy analysis — the final number can move 25% in either direction.

The peak of SaaS multiples was 2021–2022, when public hyper-growth names traded above 20x forward revenue and venture rounds priced private SaaS at 30x or more. That was a bubble fueled by zero interest rates. By 2026, the air has come out.
Median private SaaS now transacts near 6x ARR. The very best businesses — high growth, high gross margin, low churn, profitable or near-profitable — still earn 12–18x. The bottom of the market, sub-scale or low-growth SaaS, often clears at 1–3x ARR or only marginally above asset value.
The Rule of 40 says growth rate plus profit margin should be at least 40. The elegance is that it rewards both paths to a great SaaS — pure growth (60% growth, -20% margin = R40 of 40) and pure profitability (15% growth, 25% margin = R40 of 40). Either is acceptable; both is exceptional.
In this calculator, R40 directly drives the ARR multiple band. Above 80, you unlock 12–18x. 60–80 lands in 8–12x. 40–60 earns 5–8x. Below 40, multiples compress fast — 3–5x at 20–40 and 1–3x below 20.
Public SaaS comps anchor the conversation. Salesforce, HubSpot, ServiceNow, and Snowflake set the ceiling — buyers can always point to public multiples to argue your private number should be lower. The discount is typically 25–40%, sometimes more for sub-$10M ARR businesses.
The discount exists for a real reason: illiquidity, customer concentration risk, key-person risk, weaker financial controls, and the cost of due diligence. The calculator above is already calibrated to private-market reality, not public ticker prices.
After Rule of 40, the two biggest multiple modifiers are gross margin and churn. A SaaS with 85% gross margin can re-invest more aggressively and still print cash — buyers pay up for that. A SaaS at 55% gross margin is fighting infrastructure or services costs and gets discounted.
Churn is the silent killer. A business with 25% annual churn is replacing a quarter of its revenue every year before it grows a dollar. That math eventually catches up. Sub-5% annual churn is the gold standard and earns a small multiple premium.
